Effect of manganese preconditioning and replacing inorganic manganese with organic manganese on performance of male broiler chicks

Abstract

The effects of manganese (Mn) preconditioning, 96 h post-hatch followed by the replacement of inorganic Mn with different levels of organic Mn (5 to 21 D), on growth, tissue excreta Mn content, gene expression, and enzyme activity were evaluated. A total of 420 day-old male Cobb 500 broilers were divided into 2 groups. One group was fed a corn–soybean meal basal diet containing 17 mg of Mn/kg (preconditioning diet, MnPD); the second group was fed the non-preconditioning diet (NPCD), which was the MnPD supplemented with 60 mg of Mn/kg from manganese sulfate (MnSO 4 ). On day 5, each group was divided into 5 subgroups and were randomly assigned to dietary treatments consisting of MnPD alone or MnPD supplemented with 12 or 60 mg Mn/kg Mn as MnSO 4 or Mn proteinate (6 replicate cages of 6 birds). Broiler chicks that were fed the MnPD had lower ( P ≤ 0.05) body weight gain (BWG) and G:F ratio when compared to those that were fed the NPCD for 4 D. Birds that were fed MnPD (1 to 4 D) and switched to MnPD supplemented with 60 mg/kg Mn (5 to 21 D) had lower ( P ≤ 0.05) BWG compared to those that were fed NPCD (1 to 4 D) and switched to MnPD supplemented with 60 mg/kg Mn for 21 D. Excreta, tibia ash, liver, and heart Mn levels were increased ( P ≤ 0.05) by supplemental Mn. The expression of jejunum divalent metal transporter-1 mRNA levels, as well as activities of plasma total super oxide dismutase and liver alanine transaminase, was not affected by MnPD or Mn source and levels. These results confirmed that feeding marginally deficient Mn diets to broiler chicks post-hatch does affect growth rate and tissue Mn concentration.

Effects of Manganese Hydroxychloride on Growth Performance, Antioxidant Capacity, Tibia Parameters and Manganese Deposition of Broilers

“…As an essential trace element, manganese (Mn) is a component or activator of many essential enzymes, such as arginase, pyruvate carboxylase, hydrolases, etc., which are involved in carbohydrate, lipid, and protein metabolism and many crucial biochemical reactions [1,2]. It is also an essential cofactor of chondroitin sulfate synthesis that is closely related to the bone formation of broilers [3]. Otherwise, Mn plays a vital role in antioxidant Animals 2021, 11, 3470 2 of 13 and immune systems of animals [4][5][6].…”

Nutritional significance of amino acids, vitamins and minerals as nutraceuticals in poultry production and health – a comprehensive review

“…Olgun(2017) stated that the dietary addition of 90 mg Mn/kg feed prevented various disorders such as perosis, maintained normal development of broilers and improved egg shell quality parameters of laying hens. The supplementation of 12 mg Mn/kg feed from both sources (inorganic or organic) was sufficient to provide optimum broiler performance(Mwangi et al 2019). Thus, Mn in poultry nutrition is crucial due to its role in egg shell and bone development and metabolism of nutrients.…”

Efficacy of manganese pantothenate and lysinate chelates for prevention of perosis in broiler chickens

“…The results of another study (Mwangi et al, 2019) confirmed that feeding broiler chickens with a slight deficiency of manganese in the diet affects the growth rate and the concentration of this element in tissues. The addition of 75-100 mg/kg manganese to the main corn-soy diet increases overall resistance and reduces the fat deposition in broiler chickens (Ghosh et al, 2016).…”
